Lets's calculate LCM of 285,254
Given numbers has no common factors except 1. So, there LCM is their product i.e 72390
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/72390
Therefore, the GCF of Fractions 518/285,958/254 is 2/72390
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 285,254 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(285,254) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(285,254) x common factors =1 x 1 = 1
LCM(285,254) = ( 285 × 254 ) / 1
LCM(285,254) = 72390 / 1
LCM(285,254) = 72390
